Interesting Waypoint Issue

Posted by Toby Mills on July 2, 2012 at 5:19pm

I have been having this problem for a few days now.


When I write waypoints, the mission planner seems to work fine.

However, when I read them back, the waypoints are a combination of the waypoints I have just written and previous flights.


This results in scary things happening in the air.


Sometimes, when I read them back, it all looks correct, however the plane is clearly following a previous mission.

I get no errors when reading or writing waypoints.

Has anyone come across this before.

Is it an APM or mission planner issue.


I'm running 2.4 Arduplane code and mavlink 1.0 (was doing it on 0.9 as well so I upgraded).

Any ideas on how to track down what is causing this?

    some more digging on this.

    when I remove the home location and reset it again, it worked ok.
